Vehicle lamp controllers, methods for controlling vehicle lamps and vehicle lamp systems including the lamp controller and the lamps can be configured to detect whether a traveling road is a straight road or a curved road. When the traveling road is the curved road, the lamp system can direct light distribution patters from an initially light distribution angle along the traveling road with reference to a first threshold. When the traveling road is the straight road, the lamp system can direct light distribution patters from the initially light distribution angle along the traveling road with reference to a second threshold, which is larger than the first threshold. The second threshold can be changed so as to maintain preferable light distribution patterns. Thus, the present invention can provide the vehicle lamp controllers, the controlling methods for the vehicle lamps and the vehicle lamp system to form the preferable light distribution patterns.
A vehicle lamp controller for controlling a light-irradiating direction of a lamp unit in accordance with a traveling direction of an own vehicle incorporating the lamp unit and for providing the lamp unit with a driving signal so as to direct the light-irradiating direction of the lamp unit from an initial light distribution angle toward the traveling direction of the own vehicle when a traveling angle of the own vehicle is larger than thresholds, the vehicle lamp controller comprising a first threshold set up as one of the thresholds when a traveling road is a curved road, and a second threshold set up as another of the thresholds traveling road is a straight road, wherein the second threshold is larger than the first threshold.
A vehicle lamp controller for controlling a light-irradiating direction of a lamp unit in accordance with a traveling direction of an own vehicle incorporating the lamp unit, the vehicle lamp controller comprising:
A method for controlling a light-irradiating direction of a lamp unit in accordance with a traveling direction of an own vehicle incorporating the lamp unit, wherein the method is to output a driving signal to the lamp unit so as to direct the light-irradiating direction of the lamp unit toward the traveling direction of the own vehicle when the traveling angle is larger than a predetermined threshold, the control method for the lamp unit comprising:
